A quantity of gas is collected in a graduated tube over the mercury. The volume of gas at 18^(@)C is 50 mL and the level of mercuty in the tube is 100mm above the outside mercuty level. The barometer reads 750 torr. Hence, volume of gas 1 atm and 0^(@)C is approximately:

The number of molecules in 1 cm^(3) of an ideal gas at 0^(@)C and at a pressure of 10^(–5) mm of mercury is –

A long horizontal glass capillary tube open at both ends contains a mercury thread 1 m long at 0^@C . Find the length of the mercury thread, as read on this scale, at 100^@C .

The volume of a gas at 27^(@)C and 760 mm atmospheric pressure is 500 c.c. what will be the volume of the gas at 27^(@)C and 380 mm of mercury pressure?

In a constant volume gas thermometer, the pressure of the working gas is measured by the differenced in the levels of mercury in the two arms of a U-tube connected to the gas at one end. When the bulb is placed at the room temperature 27.0^0 C , the mercury column in the arm open to atmosphere stands 5.00 cm above the level of mercury in the other arm. When the bulb is placed in a hot liquid, the difference of mercury levels becomes 45..0 Cm . Calculate the temperature of the liquid. (Atmospheric pressure = 75.0cm of mercury).
